There are several laboratory works in the 8th-grade biology textbook by , R.D. Mash , and I.N. Belyaev . Since you didn't specify which one you need, I have prepared a detailed report for one of the most common and comprehensive labs: "Microscopic Structure of Bone" (Lab №4). Locate the osteons (the structural units of bone),

Biology, 8th Grade (Kolesov, Mash, Belyaev) Topic: Studying the microscopic structure of bone tissue. 1. Purpose of the Work

Although not directly visible under the microscope, the textbook notes that organic substances (collagen) give bones flexibility , while inorganic salts (calcium and phosphorus) provide hardness . 6. Conclusion Mash , and I

To study the structural features of bone tissue using a microscope, identify the relationship between the structure of bone cells and their functions, and understand the organic and inorganic composition of bones. 2. Equipment and Materials Compound light microscope. Permanent slide of "Bone Tissue" (transverse section).
